This is a follow-up to commit 9d91d371
(svx lok: draw text edits in all views, 2016-07-26). Two corner-cases
are now handled:

1) When the SfxViewShell is created after begin text edit and
2) When the other draw view is already created, but at the time begin
text edit happens, the other draw view shows a different page.

And the opposite of these: switching away from a page were we observe a
text edit done in an other view or destroying a view that observes a
text edit.

When the complete view goes away, then SdrObjEditView::HideSdrPage() is
not called, so also try to destroy the outliner view of the text edit
from SdrObjEditView::DeleteWindowFromPaintView(). The GetSfxViewShell()
call in SdrObjEditView::ShowSdrPage() is important, because we let the
other draw view create the outliner view, but the outliner view should
invoke our view shell, not the view shell of the other draw view.

Also improve the SdTiledRenderingTest::testCursorViews() testcase, so
that it asserts it managed to begin text edit and use a test document
that still has a single slide and shape, but the shape is not
auto-sized; otherwise invalidations happen even if outliner views are
not created in all draw views, so the test would pass even without the
fixes.
